I find PH is not really as important as stressed when dealing with CO2 changes. We all read that African cichlids "require" high PH but I run my planted breeding tank at PH 6.6 now and find it works for my fish.
A bit of trouble to fish holding females out of a planted tank with lots of cover but I'm willing to do the extra work to get what I want in appearance of the tank.
When it comes to water parameters, I wait to see if it works before making any real efforts to change water as it gets way too big, too fast for me to consider fighting my water and nature.
When/if I find trouble, then I will work the problem.
